1. A method of marking film-type dosage forms comprising the following steps:
placing a film-type dosage form between two layers of sealable packaging material;
sectionally heat sealing the two layers of the sealable packaging material to form an edge-sealed bag containing the film-type dosage form; and
relief embossing, using embossing tools, the film-type dosage form contained in the edge-sealed bag through at least one of the two packaging material layers of the edge-sealed bag;
wherein the relief embossing of the film-like dosage form is effected by the use of high pressure and the avoidance of heat;
wherein the sealable packaging material is a laminate including a metallic foil;
wherein the two layers of sealable packaging material are provided in the form of a strip-shaped rolled product; and
wherein the embossing tools are cooled to room temperature.
